RUBBER-ERASER HOLDER.

SPECIFICATION formingpart of Letters Patent No. 566,578, dated August25, 1896.

Application iiled April l0, 1896.

To @ZZ whom t may concern;

Be it known that l, CHARLES V. HENKEL, of New York, in the county andState of New York, have invented a new and Improved Rubber-EraserHolder, oit' Which the following is a full, clear, and exactdescription.

The object ci' this invention is to provide a superior device forholding rubber eraser-s, particularly those employed by type-Writeroperatives and draftsmen for the erasure of ink lines; and its specialobject is to provide a holder by which the eraser may be securely andfirmly held even when Worn to a very small size. This end I attain bymeans of a ilat case having a portion of its edge open, and throughwhich edge the eraser may project, the case being flexible adjacent toits open edge and being provided With a clamping device which isattached to the eraser, and which is capable of pressing the flexibleportions of the case into firm engagement with the eraser, whereby theeraser is held.

The invention will be fully described hereinafter and finally embodiedin the claims.

Reference is to be had to the accompanying dra-Wings, formingapart ofthis speciiication, in which similar characters of reference indicatecorresponding parts in all the figures.

Figure lis a perspective view of my invention. Fig. 2 is a sectionalview showing by dotted lines the position of the eraser when extended,and Fig. 3 is a sectional view taken across the device.

In the form 'of my invention shown in the drawings, the case a iscircular and provided with a closed edge h and an open edge c, the thetwo edges, respectively, occupying onehalf of the periphery of the case;and the half to which the open edge is devoted is formed on each sidewith a radial slot d, said slots being oppositely arranged and adaptedto carry a headed pin e, on which a nut f operates.

The circular case shown in the drawings is adapted for a circular rubbereraser, which is provided with a central oriiice receiving the pin e andby Which the eraser is mounted to have axial movement. The pin c iscapable of movement throughout the slots d and in so moving carries withit the eraser J. Since the slots d extend in very close proxim SerialNo. 586,980. (No model.)

ity to the open edge o, it will be observed that the center of theeraser maybe brought correspondingly near said edge, and that since theeraser may freely revolve on a ceutrally-located axis nearly all of therubber composing the eraser may be used, thereby avoiding the Waste of alarge percentage of the eraser, which Would otherwise be necessary toprovide a grasping portion for the user. The eraser g Will be freelyturned on the pin c to expose every portion of its periphery.

Fig. 2 shows in f ull lines the eraser extended beyond the edge c, so asto expose a portion of the eraser for use. In practice it will not benecessary to extend the eraser as far as the full lines in Fig. 2 show.In this view the circular dotted line g shows the eXtreme outwardposition which the eraser may ocoupy.

It will be apparent that the form of the case a may be variously changedto accommodate varying forms of the eraser.

Having thus described my invention, I claim as new and desire to secureby Letters Patentl. An eraser-holder consisting of a circular Case, aportion of the periphery of which is open and the case being iieXibleadjacent to said open portion and Vformed With radial slots, and a pinadjustably movable in said slots, the pin being capable of mounting theeraser so as to have complete axial movement and of pressing theflexible portions of the case against opposite sides of the eraser,substantially as described.

2. An eraser-holder having a ease, a portion of the edge of Which has anopening, the case being nexible adjacent to the opening, and a clampingdevice carried by the case and adjustable toward and from the opening,the clamping device being capable of connection With a rubber and alsoof pressing the flexible edges of the case against the rubber,substantially as described.

3. An eraser-holder having a case, a portion of the edge o which isopen, the case being flexible adjacent to the opening and formed withradial slots, and a pin adjusted in the slots, the pin being capable ofcarrying the eraser and having means by which the roo exible portions ofthe case may be clamped against the eraser, substantially as described.

4. An eraser-holder having a case formed With an opening in its edge andhaving a slot extending from the center of the case outwardly adjacentto the edge having the opening, and means movable in the slot, the meansbeing capable of pivotally carrying an eraser whereby the eraser may beadjusted toward and from the edge of the case and may turn freely topresent all of its edges for use, substantially as described.

5. The combination of a case having an opening in its edge and having aslot extend- -ing from said edge inward toward the center `of the case,an. eraserV contained' Within the case and capable of having a partprojected through the opening, and means movable in the slot, the eraserbeing pivotally mounted on the means and capable of movement toward andfrom the opening and of movement axilally on the said means,substantially as de- Witnesses:
